svchost error at logon and no network connections available

[Cam]

Hi,

My laptop (Tosh Sat Pro 6100 1.8GHz/1Gb) has been running
perfectly until this morning. The machine has both a
firewall (Kerio) and is running up-to-date anti-virus
software (Norton 2002).

Prior to the "Welcome to Windows" display, a "svchost.exe
Application Error (instruction 0x57d43c16 referenced
memory at 0x00000001. The memory could not be written"
message is displayed.

I am unable to see any Network Connection icons anwhere.
The devices appear in the Device Manager and can be
configured but are unable to connect to a network.

I've checked that all services are configured properly
and have tried loading the latest drivers available
(which are the ones being used previously anyway ...)

I've also followed all relevant threads in the Microsoft
KB

I can't access any of my System Restore either ...

It seems weird to be accesing an address of 0x00000001.

Any advice would be GREATLY apppreciated.

Kind regards,

Cam

Without more information it would be hard to give helpful advice.

Perhaps a repair install is in order.
